O-Feet and O-Spacers, O yeah

You may have noticed MySparcLine comes with little O-Rings.

O-Rings installed at the three touch points serve as rubber feet making resting on a surface soft & quiet. Additional O-Rings can be applied as spacers to improve the fit with devices of varying sizes. This may be helpful for very thin devices which are not in a case or for devices with a curved bottom side. Devices inside cases may tend to fit better without the O-Rings.
